| Abstract: | A new synthetic strategy was developed to prepare polymers with indole-based chromophore side chains. Thus, polymers 1 that contain indole groups as side chains was obtained by a direct reaction. And then a post azo coupling of p-nitrobenzenediazonium fluoroborate toward the indole ring in polymers 1 afforded indole-based chromophore-functionalized polymers 2. The polymers were well characterized and exhibited an excellent solubility in common organic solvents. The poled film of polymers 2 reveals a resonant d33 value of 25 pm/V obtained by second harmonic generation (SHG) measurements. |
